In the third episode of Welcome to the NHK, Sato and Yamazaki begin work on their gal game. The first step is research, which Sato does to the extreme by shutting himself in his room for an entire week and playing erotic video games and collecting internet pornography.
Then we switch gears and discuss ParaNorman, a 2012 stop-motion film about a boy who can see ghosts. His ability thrusts him into historical controversy, which nearly destroys his small Massachusetts town.
Then we finish things off with the fourth episode of Welcome to the NHK, which follows the friends as they go on a pilgrimage to an otaku section of Tokyo and make a bit of progress on their video game's main character.
